Ama-Transformer kanye namandla kagesi - izinkinga nezixazululo
1. Ikhoyili eyinhloko ye-transformer efanelekile ixhunywe emthonjeni we-voltage kanti ikhoyili yesibili ixhunywe esibanini njengoba kuboniswe ngezansi.
A. Isibani sizofiphala uma izihibe eziyinhloko zincishisiwe
B. Isibani sizokhanya kakhulu uma izihibe zesibili zanda
C. Isibani sizoba mnyama uma i-voltage eyinhloko ikhuphukile
D. Isibani sizoba lula uma izihibe eziyinhloko zincishisiwe
E. Ukukhanya kuzoba okufanayo uma izihibe zishintshwa
Isixazululo
Ushintsho enanini lama-coil loops luthinta kuphela uhlobo lwe- transformer . Uma ama-primary loops encishisiwe ukuze ama-secondary loops abe maningi khona-ke le transformer iba yi-step-up transformer ephakamisa i-voltage. Ngokufanayo, lapho ama-coil loops ehlanganiswa ukuze ama-secondary coil loops abe mancane khona-ke le transformer iba yi-step-down transformer ehlisa i-voltage.
Khumbula ukuthi lapho i-voltage yamandla ikhuphuka, amandla kagesi ayancipha ukuze amandla kagesi ahlale njalo (P = VI). Amandla kagesi ukushintsha kwamandla kagesi phakathi nesikhathi esithile. Uma amandla okufaka elingana namandla okukhipha inani lamandla asetshenziswayo nalo liyafana.
Ukukhanya okukhanyayo noma okufiphele kuhlotshaniswa namandla kagesi amaningi noma okungenani aguqulwa abe amandla okukhanya. Uma amandla kagesi amaningi eguqulwa abe amandla okukhanya khona-ke ukukhanya okukhanyayo, ngaphandle kwalokho uma amandla kagesi amancane eguqulwa abe amandla okukhanya khona-ke ukukhanya kuyafiphele. Amandla kagesi ahlala njalo, amandla kagesi nawo ayahlala njalo ngakho ukukhanya kuyafana.
Impendulo efanele ngu-E.
2. Isithombe esingezansi sichaza i-transformer efanele. Ikhoyili eyinhloko ixhunywe emthonjeni we-voltage kanti ikhoyili yesibili ixhunywe esibanini (L). Khona-ke isimo sesibani sizoba…
A. Ukukhanya okuvamile lapho kushintshwa izihibe eziyinhloko
B. Kufiphele lapho i-voltage eyinhloko ikhuphuka
C. Kukhanya lapho izihibe zesibili zanda
D. Kufiphale uma izihibe zesibili zanda
E. Kukhanya kakhulu uma izihibe eziyinhloko zincishisiwe
Isixazululo:
Amandla okufaka = P = VI = (200 Volt)(2 Ampere) = 400 Watt = Amandla okukhipha
I-transformer yehlisa i-voltage kuphela kodwa ayinciphisi amandla kagesi. Amandla kagesi agcinwa engaguquki ngakho-ke lapho i-voltage kagesi yehla, ugesi wamanje uyakhuphuka (P = VI). Amandla kagesi okufakwayo afana namandla okukhipha ngakho amandla kagesi asetshenziswa ngesikhathi esithile nawo afana. Ngakho-ke ukukhanya kuyinto evamile noma engashintshi.
Impendulo eyiyo ngu-A.
3.
Ikhoyili yesibili ixhunywe esibanini sebhalbhu, kuyilapho ikhoyili eyinhloko ixhunywe emthonjeni we-voltage. Ibhalbhu yokukhanya izovuleka...
A. kukhanya kakhulu uma inani lezihibe eziyinhloko landa
B. kukhanye kakhulu uma inani lezihibe zesibili landa
C. kukhanye kakhulu uma inani lezihibe zesibili lilingana neliyinhloko
D. kufiphele lapho i-voltage eyinhloko ikhuphuka
I-E. ifiphele lapho i-voltage eyinhloko kanye nenani lezihibe zesibili zanda
Isixazululo
Ayikho impendulo efanele
